Hi!
You can read in with textscan as strings and convert afterwards:
% read file
fid = fopen('plante1_no_head.txt');
FC = textscan(fid, '%s%s%s%s');
fclose(fid);
% first column is date as string
% second column is time as string
% third column as double
A = FC{3};
% replace ',' with '.'
A = regexprep(A, ',', '.');
% convert to numeric
A = str2num(char(A));
% fourth column as double
B = FC{4};
% replace ',' with '.'
B = regexprep(B, ',', '.');
% convert to numeric
B = str2num(char(B));
